I do have list ^^
It's a detail I always been enjoying especially in semi-comp / competitive environnement but unfortunately not happening very often. At least not in big producers' videos. You will have better luck finding this kind of natural reaction in amateur content or private sessions.
Here is a couple vids with a few comments that I can remember of and that you can easily find.
Deadle femmes - A woman Scorned (with axa!)
Fantasy wrestling
she talks to the camera, that is supposed to be a message for his girlfriend and commenting about his boner. like "see ? he is not very faithul to you"
Oil Combat - Shay hendrix vs Alex
Semi-comp / Fantasy oil wrestling
She says something like "you've got a poking out situation" at a moment.
Ashley wildcat - Training day
Semi-comp / Fantasy
Ashley notice his boner and try to teach him how to not getting hard during a session.
GrapplingGirls - GGCurvy7
Semi-comp
One of the girls is mocking him for getting a boner
GrapplingGirls - GGBBWErotic3
Fantasy
She punish him from getting a hard-on I think she says something like "How dare you getting a hard-on"
Most of the time in erotic vids ans others, Tony is getting hard but he seems to move and try to hide it from the camera. And everytime things are getting interesting the video cut right at that moment ! Which very VERY frustrating

I like the way Jade notices his boner at the end and place her foot on it, striking a victory pose.
Mutiny wrestling - MW 946
Fantasy / Semi-comp
She says something like "Babe you are so hard!"
ESB production - Emma switch - kicking his ass for having a big mouth

He is literrally poking out and she teases him at some moment.
The submission room - F534 - Humiliating Pussy boy
